Purpose
Restore saved @…GETS
Syntax
RESTORE GETS [FROM <memvar>]
See Also
@...GET, CLEAR GETS, READ, READVAR(), SAVE GETS
Description
The RESTORE GETS command allows reactivation of @...GETs previously saved with the SAVE GETS command. The optional FROM <memvar> clause can be used to restore GETS from a memory variable. This allows for multiple SAVE and RESTORE GETS. Since the Recital/4GL allows @...GET commands to be specified within a validation routine, you can execute a screen form in a procedure invoked by the @...GET...VALIDATE command. When the validation procedure is terminated, the READ in the calling screen form is reactivated. This process is called nesting reads. The RESTORE GETS command also restores the value returned by the READVAR() function.
Example
// Set up validation procedure procedure checkit parameters check save screen // Specify SAVE GETS and CLEAR GETS before @...gets save gets clear gets @1,1 get t1 @3,1 get t3 read // Reactivate reads in main screen form restore gets restore screen return @1,1 get field1 @2,1 get field2 when field1="g" @3,1 get field3 validate with checkit read
